This flight was delayed 3 or 4 times. We had boarded the plane, sat on plane for a good 30 minutes, then we had to board the aircraft, walk to a different gate, wait and then board another aircraft. We arrived in Tampa 4 hours later than the original booking. I feel there should have been some sort of compensation especially for the advantage members.
